(2x^-6y^-4z^0/3^-2x^-2y^-8z^5)^3

I entered this problem before but I entered it wrong.

I entered this problem before but I entered it wrong.

Still looks suspicious; is it:
[(2 x^-6 y^-4 z^0) / (3^-2 x^-2 y^-8 z^5)]^3 ?

And what's the question; what are you asked to do with it?

 

[Linda Long]

I am supposed to evaluate and simplify the problem.

I am supposed to evaluate and simplify the problem.

"Evaluation" is one process, involving plugging numbers in for letters. "Simplifying" is another process, not (generally) involving numbers.

What are the instructions?

Thank you.

What grade are you in, Linda?
Do you know what z^0 is equal to?

Did you know that x^-2 = 1 / x^2 ?

Are you SURE you typed it in correctly?
What does the FULL problem state?

 

[Linda Long]

The instructions say -

Simplify and Evaluate, the problem is typed exactly as on my assignment.

The instructions say - Simplify and Evaluate

Since no values are provided for the variables, following these instructions is not possible. Sorry.
